TRANSMISSION GEEASING Application filed April 1,

To all whom it may concern.

Beit known that I, ARTHUR J. Evnns, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Transmission-Greas ingAppliances, of which the following is a specification.

Autombiles or internal-combustion motor vehicles equipped with aplanetary or epicyclic transmission mechanism, such as those of the Fordtype, having a plurality of rotary drums, known respectively as thereverse drum, slow speed drum, and foot brake drum, and their encirclingcooperating expansible and contractible bands are subjectto at least oneserious disadvantage.

Even though these elements operate in oil, the linings of such bandswhich aresubject to more or less frequent use become hardened or charredor otherwise deteriorated with the result that they do not engage andrelease their respective drums smoothly and gradually, but rather theycause a violent and disagreeable chattering or vibration of the wholemechanism when starting or stopping the vehicle.

It might reasonably be assumed that the oil in the transmissioncasing orhousing would cause an easy, smooth, gradual engagement and release ofthe bands, but such is not the case after the bands have become somewhatworn.

Heretofore, it has been necessary after the bands have become thusimpaired to remove them and replace their linings with new material. s

7 Such work, however, is somewhat difiicult if done properly and isnecessarily more or less expensive and before very long the new liningswill have become deteriorated again introducing the severe and intensequivering and shaking detrimental'to the whole mechanism and extremelyunpleasant to the occupants of the vehicle. Y i

I have discoveredthat this fault and defeet in this style of mechanismmay be easily and effectively overcome or remedied atsmall cost;

Apparently the oilused in the transmissionv casing is inadequate to keepthe band linings in relatively soft and eficient condition and 'I havefound that they can be maintained insuch effective and operative statebyoccasionally applying grease to APPLIANCE.

them, such grease for instance as is ordinarily used in connection withthe lubrication of other parts of the vehicle, for example springshackle bolts, etc., such grease usually being of the generalconsistency of vaseline or possibly somewhat stiffer.

An occasional application of such grease, the frequency of use, ofcourse, depending upon the extent of travel to which the vehicle issubjected, is quite adequate to keep the car in smooth running conditionand to prolong the life of the band linings.

The improved appliance by means of which the grease is delivered to suchbands need not necessarily be'built into the car originally but may bereadily and economically applied to cars already in use.

To this end the greasing device in its simplest form is mounted on acover for the transmission casing, such cover being intended to replacethe usual cover.

It would be difiicult to apply such grease dlrectly between the bandsand their drums forming a part of this specification and to whichreference should be had in connection with the following detaileddescription .of the structure.

In this drawing, in both views of which like reference characters havebeen employed to represent the same parts,

Figure l isa central vertical section, fragmentary in character,illustrating not only the improved greasing appliance but also a portionof thetransmission mechanism in orderthat-thev relation ofthe two may befully comprehendedyand Figure'Q is a'fragmentary plan view of the coverportion of the transmission casing equipped with the greasing device.

Referring to this drawing, it will be seen that a portion 1O of the"planetary gear transmission mechanism has been shown andthat of suchmechanism parts Off the in register with the gaps between usualthreedrums 11, 12 and 13 have been illustrated, drum ll'being the reversedrum, drum 12 the slow speed drum, and drum 13 the foot brake drum, allof which is the usual construction of a Ford automobile.

'These several drums are surrounded by their respective bands 14, 15 and16 suitably lined with friction material of the ordinary nature andstructure, the ends of each band being somewhat separated as is usual,one outstandingend 17'only of each band being shown,-

The springs 18 for expanding or enlarging the bands are depicted, butthe mechanism for selectively contracting the bands individually havenot been illustrated since it is well known.

The opening in the topof the transmission casing is closed by aninclined cover 19 held fixedly in place by the usual securing screws20,20 and an aperture 21in such cover accommodates a grease-cup 22 ofsubstantialsize and appropriate shape fastened permanently to the coverby rivets 23 extended through suitable holes in the cover andalignedholes in an external flange 24 of the grease-cup, a portion ofthe latter projecting above the cover and a part 6X- tending below thesame down into the trans mission casing all as is clearly depicted inFigure 1.

The interior ofthe grease-cup is threaded at 25 with which a threadedplunger 26 coacts, the latter having an upstanding handle 27 by means ofwhich it is readily turned to force the feed of the grease or turned inthe opposite direction for its temporary removal .for refilling orreplenishing the cup.

Two spaced tubes or pipes 28 and 29 c0mmunicating with the interior ofthe grease cup project downwardly from its lower portion into the spacesbetween the three bands the up turned ends ofthe latter.

Theactual lower ends of'such tubes or conduits are closed but'one sideof member '28 has a downwardly directed. orifice 30 which delivers orfeeds the grease in a small stream on to the reverse drum 11. by whichduring ts rotation it is soon applied to the lining of the correspondingband 14.

V In somewhat similar 'inanner, the tube or pipe is supplied in itsopposite sides with a..pa1r of downwardly inclineddiverging perforations311an'd. 32-, each slightly larger indiameter than the'aperture '30 andadaptedto deliver "grease respectively to the drums 12 and'13, thelatterin turn applying it tothe linings of their surrounding hands. Inasmuchasthe reverse band and drum, are used less frequently than the others it.needs less grease to -maintain it in full opierative condition andaccordinglyorifice 30 is made: smaller than the. other two and thereforea less quantity of grease is forced through it on to thedrumthan'throughthe other apertures on to their drums.

The grease thus manually intermittently applied to the bands indirectlyby] feeding it Y to the drums doesnot take the place of the oil bath inwhich the drums revolyebut is v,

supplemental thereto.

It will. be seen that by turning the plunger slightly by handthreefstreams of grease are simultaneously delivered to the same numberofdrums or cylinders between the spaced ends of their lined bands, the

amount of grease so fed being substantially which will enable theoperator to easily apply the grease'to the band linings pref erablywithout removingv the transmission casing cover, but this maybeconveniently accomplished by means other thana greasecup or bymeanspositioned or mounted or operated other than as illustratedIanddescribed.

The cover is of proper size andshape and so supplied with holes {for thesecuring screws that it maybe easily substituted for .the usual coverover the transm ssion houslng, thus affording the'operator simple andefficient means for applying the grease at the points and tor thepurpose indicated.
